4> poison message handling, visibility extension, message encoding)
5> in the **azure-storage-queue-ts** plugin skill if installed.

7## Install
8npm install @azure/storage-queue @azure/identity
9 
10## Quick Start
11```typescript
12import { QueueServiceClient } from "@azure/storage-queue";
13import { DefaultAzureCredential } from "@azure/identity";
14const client = new QueueServiceClient(`https://${accountName}.queue.core.windows.net`, new DefaultAzureCredential());
15```
16 
17## Best Practices
18- Use DefaultAzureCredential for **local development only** — in production, use ManagedIdentityCredential. See [auth-best-practices.md](../auth-best-practices.md)
19- Always delete after processing — prevent duplicate processing
20- Handle poison messages — move failed messages to a dead-letter queue
21- Use appropriate visibility timeout — set based on expected processing time
22- Extend visibility for long tasks — update message to prevent timeout
23- Use JSON for structured data — serialize objects to JSON strings
24- Check dequeueCount — detect repeatedly failing messages
25- Use batch receive — receive multiple messages for efficiency
